Application filed February 24, 1920. Serial No. 360,966.

To all whom it may concern.

Be. it known that I, ADDISONE. AUGUS- TINE, residing at Hackensack, inthe county of Bergen and State of New Jersey, have invented certain newand useful Improvements in Removable Drying-Chain Mechanism forEnvelope-Making Machines, of

a removable drying chainmechanismcomprising one or more main frameelements adapted to carry the chain and other parts ofthe [dryingmechanism, andto so construct and arrange these frame elements that theyare supported by the main frame of the machine ina position to hold thechain in cooperative relationwith other elements of the ma-,

chine and yet be capable of bodily removal without necessity forderanging the adjustment of any of the adjacent elements of the machine.

Other objects and aims of the invention, more or less specificpthanthose. referred to above, will be in part obvious and in part pointedout in the course of the following description of the elements,combinations, arrangements of parts and" applications of principles,constituting the invention, and the scope of protection contemplatedwill be indicated in the appended claims.

In the accompanyingv drawings which are to be taken as apart of thisspecification, and in which I have shown merely a preferredformofembodiment" of the invention:-- i

Figure 1 is a side elevational view of a drying chain mechanismconstructed and arranged in accordance with this invention; a

Figure 2 is a top plan view' -of the mechanism seen in Fig. '1], adjacent' portions of the envelope making machine being shown in horizontalsection. j

re 3 is" a side elevational view of one Figure 4 is a transverse 1sectional view taken substantially upon theplane of line IV of Fig. 1.

Referrin in detail t e structure which is illustrated to the drawingsfor describing therein, the reference character L indicates the mainframeof the envelope-making machine. v trap dischargedevice is indicatedat 1 by which the folded and newly gummed envelopes are delivered intothe spaces, as

i A shaft 5 is shown for drivingthe chain G. This shaft has a smallsprocket 6 thereon about which the'links of the chain move so that inrounding theshaft the fins 3,'one of whichis carried by each'link' ofthe chain,

spread apart as clearly seen at the upper end of Fig: 1 for receivingthe envelopes from "the trap.

The chain moves usually with a step by a step movement in the directionofthe arrows so that the envelopes from thetrap' 1 are carrieddownwardly along the upper lead of the chain, aroundthe lower roller 7andthence upwardly along the lower lead of the chain.

Any suitable means may beprovided for delive'ring, orejecting, theenvelopes from the upper end ofthe lowerlead of the chain, as

indicated the "arrow 8 at this point,

During the travel of the envelopesalong the upper lead of the chaintheir-weight rests I upon the links of the chain, and suitable guiderods 9 are provided at opposite sides of the chain for preventingendwise displacement of the envelopes. As theenvelopes round the wheel 7their weight falls away fromthe chain and on to suitable guide rods 10which continue parallel with the chain upwardly to a point where theenvelopes are ejected, as abovementioned'. The guide rods wardlyparallel with the rods 10.

su ported, as at 12, in the frame 8, suitable 9 are continued around thewheel and up adjusting screws 13 being provided for moving the wheel? toproperly chain. G.
